How to generate unique file names with SimpleUploads

If for any reason you can't change the server back-end that saves your file uploads in CKEditor and you want to prevent the overwriting of existing files with new ones that have the same file names, you can add this code to your page to generate a unique filename for each upload (adjust it to your tastes)

CKEDITOR.on('instanceReady', function (e) {
 e.editor.on('simpleuploads.startUpload', function (ev) {
  var filename = ev.data.name;
  //var extension = filename.match(/\.\w+$/)[0];
  var newName = CKEDITOR.plugins.simpleuploads.getTimeStampId() + '_' + filename;
  ev.data.name = newName;
 });
});
